Description

Technical Field

[0001] This invention belongs to the field of aircraft emergency rescue technology, and in particular relates to an emergency rescue platform. Background Technology

[0002] Aircraft landing gear can be divided into two parts: main landing gear and nose landing gear. Nose landing gear: a ground support component mounted under the nose of the aircraft, which mainly serves a guiding function in addition to supporting a small portion of the gravity load; main landing gear: usually located near the center of gravity of the aircraft, is a key component that bears most of the weight of the aircraft.

[0003] During landing, aircraft may experience accidents such as tire blowouts or landing gear failures due to pilot error, equipment malfunction, or severe weather conditions. Emergency aircraft rescue operations require the rapid and safe removal of damaged or malfunctioning aircraft from the runway or apron.

[0004] Existing rescue equipment cannot handle both front landing gear and main landing gear malfunctions simultaneously. Different equipment is required for these two types of malfunctions, and it is not possible to quickly adjust and replace them to adapt to different application scenarios.

[0005] Meanwhile, the nose landing gear and main landing gear are installed at different heights, making it difficult for a single rescue device to be raised to different heights to accommodate the different landing gear supports; in addition, the fuselage shape of landing gear accessories varies between different aircraft models, and existing rescue devices cannot flexibly adapt to different fuselage shapes.

[0006] To address this issue, the inventors have provided an emergency rescue platform for supporting an aircraft after damage to its nose or main landing gear, and for moving the aircraft to a safe area under the towing of a tractor. This emergency rescue platform can replace the landing gear function, providing support and steering for the aircraft; it also has adjustable support height to support different aircraft types and facilitate aircraft relocation. Summary of the Invention

[0007] The purpose of this invention is to provide an emergency rescue platform for supporting an aircraft after damage to the nose or main landing gear, and for moving the aircraft to a safe area under the towing of a tractor. The main function of this emergency rescue platform is to replace the landing gear, providing support and steering for the aircraft, while also having adjustable support altitude to support different aircraft types and facilitate aircraft relocation.

[0010] Furthermore, a sliding groove is provided on one side of each of the two main lifting support surfaces, and a pulley is provided on the sliding leg corresponding to the position of the sliding groove. The sliding leg is slidably connected to the main lifting support surface through the pulley and the sliding groove, and the hinge end of the rotating leg is located on the connecting bracket between the two main lifting support surfaces.

[0011] Furthermore, a through first pin hole is provided above the main support surface corresponding to the position of the slide groove, and the sliding leg and the main support surface are limited by inserting a first pin into the first pin hole.

[0012] Furthermore, both the sliding leg and the rotating leg are X-shaped frame structures, and the rotating leg has a support plate on its outward-facing side, with a removable rubber pad on the support plate.

[0013] Furthermore, the front support surface, the main support surface, and the support plate are all provided with multiple sets of insertion holes for installing corresponding pads.

[0014] Furthermore, both the main lifting pad and the front lifting pad are provided with curved surfaces corresponding to the fuselage arc.

[0015] Furthermore, the hydraulic lifting assembly includes a hydraulic cylinder, a hand pump, and a hydraulic auxiliary assembly. The hydraulic cylinder, the hand pump, and the hydraulic auxiliary assembly are connected by pipelines. One end of the cylinder seat of the hydraulic cylinder is fixed on the base frame, and one end of the piston rod of the hydraulic cylinder is connected to the support platform. The hand pump is fixed on the base frame.

[0016] Furthermore, the base frame is a grid-shaped frame structure, and the bottom of the four column sleeves of the telescopic frame are respectively fixed to the four corners of the base frame. The four telescopic rods are respectively inserted into the four column sleeves of the telescopic frame.

Detailed Implementation

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] See Figures 1-8 The present invention provides a technical solution: like Figures 1-2 As shown, an emergency rescue platform includes a base frame 1 and a lifting mechanism 2, a platform 3, and a folding bracket 4 located above the base frame 1. The lifting mechanism 2 includes a telescopic frame 21, a telescopic rod 22, and a hydraulic lifting assembly 23. The bottoms of the telescopic frame 21 and the hydraulic lifting assembly 23 are fixed to the base frame 1. The platform 3 is fixed to the top of the telescopic rod 22 and connected to the top of the hydraulic lifting assembly 23. The platform 3 is raised and lowered by the lifting mechanism 2. The platform 3 is provided with a detachable main lifting pad 9. The folding bracket 4 is movably connected to the platform 3. The front end of the base frame 1 is provided with a traction mechanism 5, and the bottom of the base frame 1 is provided with casters 6.

[0024] Using the above technical solution, the emergency rescue platform moves via the casters 6 under the base frame 1 and is connected to the trolley via the traction mechanism 5 at the front end of the base frame 1 for towing operations. The aircraft support platform 3 and folding bracket 4 above the base frame 1 are raised and lowered via the lifting mechanism 2, thereby raising them to a suitable height to contact the underside of the aircraft fuselage.

[0025] The aircraft support platform 3 is equipped with a main landing gear pad 9 that conforms to the fuselage arc to support the fuselage in the event of a main landing gear failure. At this time, the emergency rescue platform replaces the faulty main landing gear for transfer. After the folding bracket 4 is raised and unfolded, it is equipped with a front landing gear pad 8 to support the fuselage in the event of a front landing gear failure. At this time, the emergency rescue platform replaces the faulty front landing gear for transfer.

[0026] The emergency rescue platform of this invention can be used to rescue those with front landing gear failure or main landing gear failure, improving the versatility of the equipment and adapting to different aircraft models.

[0027] Specifically, such as Figures 3-4 As shown, the lifting platform 3 includes a connecting bracket 32 ​​and main lifting support surfaces 31 located on both sides of the connecting bracket 32. The top of the telescopic rod 22 is fixed to the bottom of the main lifting support surface 31, the top of the hydraulic lifting assembly 23 is fixed to the middle of the connecting bracket 32, and the folding bracket 4 is located between the two main lifting support surfaces 31.

[0028] like Figure 1 and Figure 3 As shown, the folding bracket 4 includes a front support surface 41, a sliding leg 42, and a rotating leg 43. One end of the sliding leg 42 is hinged to the front support surface 41, and the other end of the sliding leg 42 is slidably connected to the carrier platform 3. One end of the rotating leg 43 is fixedly connected to the front support surface 41 in a figure-7 arrangement, and the other end of the rotating leg 43 is hinged to the carrier platform 3. The folding bracket 4 is folded by the sliding leg 42 and the rotating leg 43. A detachable front support pad 8 is provided on the front support surface 41.

[0029] Furthermore, such as Figure 4 As shown, a groove 33 is provided on one side of each of the two main support surfaces 31 facing each other. Figure 5 As shown, the sliding support leg 42 is provided with a pulley 45 at the position corresponding to the sliding groove 33.

[0030] Continue as Figure 3 As shown, the sliding support leg 42 is slidably connected to the main support surface 31 via the pulley 45 and the sliding groove 33, and the hinge end of the rotating support leg 43 is located on the connecting bracket 32 ​​between the two main support surfaces 31.

[0031] Through the above technical solutions, and as Figure 7As shown, the folding bracket 4 unfolds into a triangular structure. At this time, the front support surface 41 is located at the top, and the sliding leg 42 and the rotating leg 43 are located on both sides. Since the main support surface 31 has a through first pin hole at the position corresponding to the slide groove 33, after the sliding leg 42 is unfolded, the first pin 34 is inserted into the corresponding first pin hole to limit the pulley 45 of the sliding leg 42 in the slide groove 33, so that the sliding leg 42 will not retract.

[0032] After the folding support 4 is deployed, the nose support surface 41 abuts against the fuselage, causing the folding support 4 to bear load. The aircraft's gravity acts on the nose support surface 41 of the rotated and deployed folding support 4. The load is transmitted through the sliding outriggers 42 and rotating outriggers 43 to the aircraft support platform 3 and the four telescopic rods 22 and telescopic frame 21 below, maintaining the overall structural stability. Simultaneously, a nose support pad 8 conforming to the fuselage shape is installed on the nose support surface 41. The surface of the nose support pad 8 is made of rubber to increase friction, and under the action of the lifting structure, the nose support pad 8 is kept close to the fuselage, preventing the aircraft from sliding horizontally on the nose support pad 8. When the towing equipment moves the emergency rescue platform, the force exerted by the aircraft in the horizontal direction on the folding support 4 is prevented from falling over by the first pin 34.

[0033] Furthermore, such as Figure 5 and Figure 7 As shown, both the sliding leg 42 and the rotating leg 43 are X-shaped frame structures, which are supported by internal X-shaped rods to maintain stability and improve connection strength.

[0034] like Figure 5 and Figure 8 As shown, a support plate 44 is provided on the outward-facing side of the rotating outrigger 43, and a removable rubber pad 7 is provided on the support plate 44. When supporting the main landing gear, the rubber pad 7 plays a role in assisting in supporting the fuselage. At the same time, rubber pads 7 of different thicknesses can be replaced, and different main landing gear pads 9 can be used to adapt to different fuselage curvatures.

[0035] Furthermore, the front start support surface 41, the main start support surface 31, and the support plate 44 are all provided with multiple sets of insertion holes for installing corresponding pads. The pads on the corresponding support surfaces or support plates 44 can be quickly installed through the insertion holes. Different fuselage types can be adapted by replacing the main start pad 9, the front start pad 8, and the rubber pad 7. At the same time, the main start pad 9 and the front start pad 8 are both provided with curved surfaces corresponding to the fuselage arc, which can be replaced to fit different aircraft.

[0036] The rubber parts of the main lifting pad 9, the front lifting pad 8, and the rubber pad 7 are made of rubber with a high surface vulcanization friction coefficient. While ensuring the strength of the supporting structure, they protect the aircraft skin and improve static friction, which can effectively prevent the emergency rescue platform from detaching from the aircraft during towing.

[0037] Furthermore, such as Figure 1 and 2 As shown, the hydraulic lifting assembly 23 includes a hydraulic cylinder 231, a hand pump 232, and a hydraulic auxiliary assembly. The hydraulic cylinder 231, the hand pump 232, and the hydraulic auxiliary assembly are connected by pipelines. One end of the cylinder seat of the hydraulic cylinder 231 is fixed on the base frame 1, and one end of the piston rod of the hydraulic cylinder 231 is connected to the support platform 3. The hand pump 232 is fixed on the base frame 1.

[0038] Through the above technical solution, the lifting of the emergency rescue platform adopts a hydraulic lifting mechanism based on a hand-cranked pump 232. Compared with an electric lifting structure, it has advantages such as simplicity, quick use, convenient maintenance, and stability and reliability. According to the equipment's workflow, one person can complete the lifting operation using the hand-cranked pump 232. It can be seen that an electric lifting mechanism 2 can also be used to improve lifting efficiency.

[0039] Furthermore, such as Figure 6 As shown, the base frame 1 is a grid-shaped frame structure. The bottom of the four column sleeves of the telescopic frame 21 is fixed to the four corners of the base frame 1 respectively. The four telescopic rods 22 are respectively inserted into the four column sleeves of the telescopic frame 21. The telescopic rods 22 and the corresponding column sleeves are evenly provided with second pin holes of the same size and specifications. The telescopic rods 22 and the column sleeves of the telescopic frame 21 are fixed by inserting the second pins 24 into the second pin holes.

[0040] Through the above technical solution, the base frame 1 and the telescopic frame 21 are made of high-quality carbon structural steel. The base frame 1 is welded from the selected profiles, which ensures strength and can also distribute the weight evenly to the four casters 6, ensuring the smooth movement of the emergency rescue platform during traction.

[0041] Specifically, the telescopic pole 22 and the telescopic frame 21 are the main load-bearing components of the emergency rescue equipment, providing the main support for the equipment. The telescopic frame 21 is welded from four 100×100×8 square tubes and a 40×40×4 square tube, while the telescopic pole 22 is welded from an 80×80×8 square tube and an upper platform connecting plate. Each hole on the telescopic pole 22 is marked with its position; this marking allows for easy location during hydraulic lifting, facilitating equipment use. The hydraulic lifting stroke can reach 400mm.

[0042] The folding bracket 4 can be folded to a height of 600mm, and the lifting mechanism 2 can be folded to a height of 400mm. When the emergency rescue platform is folded up, its dimensions are ≤1100mm×1000mm×1000mm, and its height is reduced to 50% of its maximum height.

[0043] Furthermore, the traction mechanism 5 includes a traction lug 52 and a connecting rod 51, wherein the connecting rod 51 is movably connected to the traction lug 52.

[0044] Through the above technical solution, the traction lug 52 is made of Q345 steel, which has high overall strength.

[0045] Furthermore, the caster wheel 6 is a heavy-duty caster wheel 6, the wheel body of the caster wheel 6 is made of nylon, and the two rear caster wheels 6 are equipped with a braking structure.

[0046] The above technical solutions ensure that the emergency rescue platform will not damage the paint on the deck or runway during operation. When the landing gear rescue platform supports the aircraft, the omnidirectional casters ensure the flexibility of wheel steering, guaranteeing smooth traction and preventing jerking. The two rear wheels are equipped with brakes to secure the emergency rescue platform during docking with the aircraft, preventing the platform from shifting under load and causing docking failure.

[0047] The specific workflow of the emergency rescue platform is as follows: like Figure 7 As shown, when supporting the nose landing gear, if the nose landing gear is damaged, a crane is used to level the aircraft or airbags are used to lift it. While leveling the aircraft, personnel quickly push the emergency rescue platform next to it. Once the aircraft's attitude is back to level, it is pushed into the designated rescue frame position on the nose landing gear. The folding support 4 is quickly unfolded and locked with the first pin 34, and the corresponding nose landing pad 8 is installed. Then, the hand pump 232 is used to pressurize the hydraulic cylinder 231, causing the aircraft support platform 3, folding support 4, and the nose landing pad 8 above the folding support 4 to gradually rise. When the platform reaches the designed height, pressurization is stopped, and the four telescopic rods 22 are locked using the second pin 24 provided with the equipment. The position of the rescue platform is quickly and finely adjusted to ensure the nose landing pad 8 fits the aircraft frame more closely. The aircraft is lowered by a crane or the airbags are deflated, leaving the front of the aircraft completely supported by the emergency rescue platform, which fully bears the weight of the front of the aircraft. The rescue platform is then secured to the aircraft with straps. Use the remaining straps to connect and secure the emergency rescue platform to the main landing gear on both sides. At this point, the tow bar of the towing vehicle can be connected to tow the aircraft.

[0048] When the aircraft is lowered, because the front landing pad 8 is curved, the aircraft's own weight will cause the front landing pad 8 to fit the curved surface of the aircraft, making the rescue platform fit the aircraft more tightly.

[0049] The towing vehicle is connected to the towing lug 52 at the front end of the base frame 1 via a towing rod. When the towing vehicle tows, the traction force on the equipment can be transmitted to the main landing gear of the aircraft through the straps, reducing the towing burden on the rescue platform and effectively preventing secondary separation of the rescue platform from the non-rigid connection with the aircraft.

[0050] like Figure 8 As shown, when supporting the main landing gear, if one side of the main landing gear is damaged, the aircraft is restored to a level attitude in the same way. While lifting the aircraft, the emergency rescue platform is moved to one side of the aircraft, and a main landing gear pad 9 is installed on the main landing gear support surface 31, while rubber pads 7 are installed on the support plate 44. After assembly, the rescue platform is pushed under the engine support frame next to the main landing gear, and pressurized to the set height using a hand pump 232. The surrounding telescopic rods 22 are then locked with second pins 24. The aircraft is then lowered, at which point the emergency rescue platform fully bears the weight of one side of the aircraft. The emergency rescue platform is then secured to the aircraft with straps, and the remaining straps are used to connect and secure the emergency rescue platform to the nose landing gear. After securing, the aircraft can be moved by towing the nose landing gear with a tow truck.

[0051] When the towing vehicle tows the aircraft, the traction force is transferred to the emergency rescue platform through straps, causing the platform to move with the aircraft and preventing the aircraft and rescue equipment from becoming detached. This also prevents secondary damage to the aircraft.

[0052] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
